Description

污渍去除装置 技术领域
本发明涉及一种小型的污渍去除装置,其可以对布制品进行局部敲打清洗,能自动进行对布制品上出现的污渍部分的液体供给以及敲打力的赋予。
背景技术
在脏污局部附着在布制品上形成污渍的情况下,一般而言,相比整体清洗该布制品,从去污效果、操作效率方面来看,仅对污渍部分进行清洗处理更佳,而作为可局部清洗布制品的装置可以例举出非专利文献1的污渍去除系统。
非专利文献1的污渍去除系统由收容去污剂的瓶体和吸纳片构成,在瓶体的顶端形成有用于供给去污剂的细孔。该污渍去除系统能在将吸纳片与下方抵接的状态下以所述瓶体的顶端敲打污渍部分,利用该敲打动作供给去污剂给污渍部分。供给的去污剂浸透到布制品中,与构成污渍部分的脏污一同被吸纳到吸纳片中。
然而,这样的非专利文献1的污渍去除系统由于需要使保持瓶体的手迅速地上下移动,因此存在手疲劳的问题。
另一方面,在专利文献1中公开了一种污渍去除装置,通过按压开关,能向衣物的污渍部分喷出溶剂,并且,通过因风扇的负压而产生的吸引作用,能与溶剂一起将脏污从衣物的污渍部分去除。由于通过该污渍去除装置,可以自动涂敷溶剂到衣物上以及自动吸引(去除)已涂敷的溶剂,因此不需要对污渍部分反复手动施加敲打力,不会发生因迅速移动手而而导致的手的疲劳。
然而,专利文献1中公开的结构,由于不是对污渍部分施加物理力的结构,因此,例如在污渍部分附着了难以与溶剂融合的固体脏污的情况下,可能去除污渍需要花费时间,也可能不能完全去除污渍。即,专利文献1中公开的结构称不上具有足够的污渍去除能力,为了发挥高污渍去除能力,优选如非专利文献1那样的,可以对污渍部分施加敲打力从而物理粉碎固体脏污的结构。此外,专利文献1中公开的结构,由于具有喷射溶剂的机构、风扇等,因此部件件数变多,装置易变得大型,难以制成方便携带的结构。

发明内容
发明所要解决的问题
本发明的目的在于有效地解决这样的问题,目的在于供给一种污渍去除装置,该污渍去除装置能对污渍部分自动赋予敲打力并发挥高污渍去除效果,并且可以实现小型化。
用于解决问题的方案
本发明鉴于以上的问题,提出了如下的方案。
即,本发明的污渍去除装置,其特征在于,具备:头部,形成有敲打面;振动单元,位于与所述敲打面正交的所述头部的轴线的延长线上,通过电磁致动器的驱动使所述头部往轴线方向振动;液体用收容部,能收容液体;以及液体供给单元,伴随着通过所述振动单元产生的所述头部的振动,供给所述液体用收容部内的所述液体给所述敲打面。
此外,本发明可以考虑具备:主体壳体,所述头部从所述主体壳体的前端部突出;以及罩部,具备有多个,可装卸在所述主体壳体的前端部,且在所述电磁致动器的工作行程的范围内,各个所述罩部在所述轴线方向上的长度不同,在已将所述多个的罩部的任一个安装在所述主体壳体的前端部的状态下使用本发明的污渍去除装置。
或者本发明可以考虑采用如下结构:具有主体壳体,所述头部从所述主体壳体的前端部突出;以及罩部,可装卸在所述主体壳体的前端部,在所述主体壳体以及所述罩部形成有变更部,该变更部能够在所述电磁致动器的工作行程的范围内,变更所述罩部从所述主体壳体的所述前端部突出的长度。
此外,本发明优选采用如下结构:在所述主体壳体的前端部或所述罩部的基端部的任意一方,作为所述变更部,形成有往所述轴线方向延伸的凸部,并 且,在所述主体壳体的前端部或所述罩部的基端部的任意另一方,作为所述变更部,形成有具有大致整个所述凸部所卡合的深度的第一凹部以及比该第一凹部浅的第二凹部,在使所述凸部与所述第一凹部卡合的情况和与所述第二凹部卡合的情况下,能够变更所述罩部的突出长度。
在该结构中,本发明优选在所述主体壳体的前端部或所述罩部的基端部的一方,形成有可弹性变形的爪部,并且在所述主体壳体的前端部或所述罩部的基端部的另一方,在所述凹部与所述凸部卡合的位置形成有与所述爪部扣合的扣合部。
此外,本发明优选采用如下结构:在所述主体壳体或所述罩部的任意一方的外圆周面上,作为所述变更部,形成有螺钉部,并且,在所述主体壳体或所述罩部的任意另一方的内圆周面上,作为所述变更部,形成有与所述螺钉部对应的螺母部,通过增减所述螺钉部拧入所述螺母部的拧入量,能够变更所述罩部的突出长度。
本发明尤其优选如下结构:所述电磁致动器赋予动铁芯离开所述头部的方向的吸引力,所述振动单元具有使所述头部往与所述动铁芯的位移方向相反的方向突出的联杆机构。
发明效果
根据如上所说明的本发明,由于振动单元能通过电磁致动器的驱动使头部振动,同时从液体供给单元供给液体用收容部内的液体给头部的敲打面,因此使头部敲打污渍去除对象物的动作机械化(自动化),无需迅速移动手就发挥高污渍去除效果。此外,由于能将往电磁致动器的直线方向的驱动力直接利用于头部的振动,因此无需像例如将电机用作驱动源的情况那样,设置将电机的旋转力变换成直线方向的力的齿轮等减速变换机构,能减少部件数从而实现紧凑化(小型化)。
此外,根据在已将所述轴线方向上的长度不同的多个罩部的任一个安装在所述主体壳体的前端部的状态下使用的本发明,由于能够根据所安装的罩部而变更从主体壳体的前端部到污渍去除对象物的距离,因此能机械式地改变电磁致动器的工作行程,调整头部对污渍去除对象物施加的敲打力的强度。
或者,根据形成有能够变更所述罩部从所述主体壳体的所述前端部突出的长度的变更部的本发明,由于能根据罩部的突出长度,变更从主体壳体的前端 部到污渍去除对象物的距离,因此能机械式地改变电磁致动器的工作行程,调整头部对污渍去除对象物施加的敲打力的强度。
特别是,根据能够在使所述凸部与所述第一凹部卡合的情况和与所述第二凹部卡合的情况下变更所述罩部的突出长度的本发明,由于相对较深的凹部卡合了大致整个凸部,而相对较浅的凹部只卡合了凸部的前端部,罩部的突出长度只长到这种程度,因此能轻易地由一个罩部调整敲打力的强度。
进而,根据在所述凹部和所述凸部嵌合的位置形成有与所述爪部扣合的扣合部的本发明,由于罩部经由爪部以及卡合部,在轴线方向上固定于主体壳体,因此能防止罩部在污渍去除操作中从主体壳体上脱落。
此外,根据通过增减所述螺钉拧入部所述螺母部的拧入量,能够变更所述罩部的突出长度的本发明,能连续地变更罩部的突出长度,能轻易地由一个罩部调整敲打力的强度。
特别是,根据所述振动单元具有使所述头部往与动铁芯的位移方向相反的方向突出的联杆机构的本发明,在电磁致动器发挥最强力时,即电磁致动器的动铁芯被抬至最高时,能经由联杆机构使头部突出,能提高敲打力。

具体实施方式
以下,参照附图对本发明的一实施方式进行说明。
图1是表示本发明的一实施方式的污渍去除装置100的外观的主视图。图2是表示本实施方式的污渍去除装置100的纵剖视图。图3是表示从构成本实施方式的污渍去除装置100的主体壳体33取下的状态的液体用收容部12以及保护罩5的主视图。
如图2所示,污渍去除装置100具有装置主体1、盖构件6以及保护罩(导向装置)5。
装置主体1具有头部11、液体供给单元20、振动单元4、电池32、以及在内部组装有这些组成部件的有底圆筒状的主体壳体33。
头部11具有敲打部21以及头部插入部22。敲打部21为形成有敲打面21a的纵剖面大致半圆的,更详细地说比起半圆稍微近似圆形的部件。这样的头部11位于主体壳体33的端面的中心。
头部插入部22是从敲打部21延伸,可拔插地插入后述的被插入部25中的部件,头部插入部22的侧面具有在振动方向上相互分开地形成的未图示的多个圆环状的突出部分。当头部插入部22向被插入部25插入时,通过所述突出部分按压被插入部25的内面,即使反复进行多次装卸,也能够固定程度不变地稳定地固定头部11于被插入部25。
需要说明的是,虽然在本实施方式中头部11为树脂(例如尼龙)制,但材质并不局限于树脂,也可以是金属(例如不锈钢(Stainless Used Steel:sus))等。
如图2、3所示的液体供给单元20具有液体用收容部(水瓶)12和供水路13。
液体用收容部12具有液体储藏部24以及被插入部25。液体储藏部24是能收容液体的透明或半透明的空芯状的部件,在头部11侧的前端部通过螺钉固定的方式安装有盖构件24a。通过取下该盖构件24a,能在收容液体用收容部12内收容液体。此外,液体储藏部24构成为轴线方向上的一部分的径向小,并设 有能与后述的卡定爪45b(参照图4等)卡合的卡定凹部12a。在这样的液体储藏部24形成有向头部11呈锥状开口的圆筒给水孔28。液体储藏部24内的液体从圆筒给水孔28向下流过供水路13从而供给到敲打面21a。
被插入部25从液体储藏部24延伸,头部11的头部插入部22通过轻轻压入,可拔插地插入被插入部25。需要说明的是,头部插入部22不局限于通过压入方式插入被插入部25,也可以通过螺钉固定的方式插入。
此处作为液体,能使用水、按照一定比例将水以及洗涤剂混合的洗涤剂混合液、乙醇或汽油等普通溶剂、或者污渍去除用专用洗涤剂等。在本实施方式中,作为收容于液体储藏部24的液体只使用水。
图2所示从液体储藏部24至敲打面21a,贯通头部11地形成有供水路13,将液体用收容部12内的液体提供给头部11的敲打面21a。在供水路13局部形成有比其他部分的流路截面小的小径部分27c。
在这样的供水路13中留存有从液体储藏部24滴下的液体。供水路13在头部11振动的状态下,以稳定的流量将液体一点点地少量(例如1~1.5cc/min)排出到头部11的敲打面21a。另一方面,在头部11不振动的状态下,特别是在小径部分27c,通过表面张力防止液体的滴下。
图2所示的振动单元4位于与敲打面21a正交的头部11的轴线S的延长线上,通过使用电池32的电力的电磁致动器(solenoid actuator)41的驱动,经由开口33a使比主体壳体33的前端部33b突出的头部11往轴线方向振动。电池32在本实施方式中为充电电池,经由形成于主体壳体33局部的未图示的开闭盖收容在主体壳体33内。以下,有时会将头部11的轴线方向称为振动方向。此外,振动方向中,将头部11向装置外突出的方向称作突出方向Z1,其相反的方向称作返回方向Z2。此外,将图2的纸面垂直方向称作第一方向Y。进而,将与振动方向以及第一方向Y正交的方向称作第二方向X。
电磁致动器41具有动铁芯41a,该动铁芯41a通过对未图示的线圈的通电被交替切换为ON或OFF而往振动方向移动。动铁芯41a的轴线设定在头部11的轴线S的延长线上。振动单元4使头部11振动的具体结构会在后面进行叙述。
盖构件6能够从主体壳体33的前端部33b装卸,在进行后述的污渍去除操作时如图2所示从装置主体1取下。此外,盖构件6在携带污渍去除装置100时被安装在装置主体1上,能有效地防止向装置外的漏水、对头部11的冲击等。
作为罩部的保护罩5为树脂制的非挠性且大致圆筒形的透明构件,在包围头部11的侧面的位置,如图2所示,经由筋33a1可装卸地安装在主体壳体33的前端部33b。该保护罩5的长度(高度)设定为当以最大的工作行程移动了动铁芯41a时,头部11在突出方向Z1上的动作端比保护罩5的突出端51稍稍突出。
通过具备这样的保护罩5,在后述的污渍去除操作过程中,保护罩5能遮挡通过头部11的振动而飞散的液体,防止液体大范围扩散。因此,能缩小衣物C被浸湿的面积,可以在污渍去除操作后立即穿上衣物C。
这样的污渍去除装置100是可以局部清洗作为污渍去除对象物的衣物C的手持尺寸的装置。在进行污渍去除操作时,吸收垫衬P作为衬垫抵接在衣物C的污渍部分sp的下方,并且污渍去除用洗涤剂直接涂覆在衣物C的污渍部分sp。并且,污渍去除装置100以保护罩5的突出端51在头部11的敲打面21a与污渍部分sp对置的位置被按压在衣物C上的方式进行使用。需要说明的是,此时也可以不使用洗涤剂。
当在该状态下操作电源开关Sw时,电磁致动器41通过来自电池32的供电驱动,在轴线方向上进行直线运动的动铁芯41a的驱动力使头部11振动,通过敲打面21a对污渍部分sp赋予敲打力。
当使装置主体1沿着衣物C移动并且重复这样的动作时,供给到污渍部分sp的液体(在本实施方式中为水)与涂敷在污渍部分sp的洗涤剂一起溶解构成污渍部分sp的脏污并将其从衣物C中敲打出来由吸收衬垫P吸收。即污渍去除装置100通过施加敲打力将衣物C的脏污与液体以及洗涤剂一起转移到吸收衬垫P,去除污渍。
需要说明的是,作为吸收垫衬P不特别限定,只要液体的吸收速度快就能使用各种物品,例如能使用折叠了厨房纸巾后的产物。
如上所述的污渍去除装置100具备:头部11,形成有敲打面21a;振动单元4,位于与敲打面21a正交的头部11的轴线S的延长线上,通过电磁致动器41的驱动使头部11在轴线方向上振动;以及液体供给单元20,具有可收容液体的液体用收容部12,伴随着通过振动单元4产生的头部4的振动,供给液体用收容部12内的液体给敲打面21a。
当采用这样的结构时,由于振动单元4通过电磁致动器41的驱动使头部11振动,并且从液体供给单元20供给液体用收容部12内的液体给头部11的敲打面21a,因此头部11能自动进行敲打作为污渍去除对象物的衣物C的动作,无需迅速移动收就发挥高污渍去除效果。此外,由于向电磁致动器41的直线方向的驱动力被用于头部11的振动,因此无需像例如将电机用于驱动源的情况那样,设置将电机的旋转力变换为直线方向的力的齿轮等减速变换机构。因此,污渍去除装置100能减少部件件数,简化结构,并且能大幅缩小主体壳体33的直径,能实现紧凑化。
如此,本实施方式的污渍去除装置100紧凑且便携性良好,当在外出地时食物残渍、化妆品等附着在布制品上时,通过利用局部清洗,能使污渍不明显。另外,能局部地适当清洗窗帘、地毯等不容易整体清洗的物品。进而,污渍去除装置100还能适用于在利用洗衣机进行洗涤的前期,对衣物C的衣领、袖口等处的脏污进行预先清洗。

如图5(b)所示,振动单元4具有上述的电磁致动器41、螺旋弹簧46、联杆机构40以及活塞45。
联杆机构40如图4~6所示具有电磁连结部42、联杆部43、活塞固定部44。
电磁连结部42如图6所示,具有:固定侧基部42a,其为与图2所示的敲打面21a大致平行的板状构件;突出方向延伸突出部分42b,从固定侧基部42a的第一方向Y上的两端部分别往突出方向Z1延伸;以及卡合销42d,贯通后述的长孔42c。在固定侧基部42a的中心部,形成有嵌入有螺旋弹簧46的动铁芯41a所贯通的圆形的铁芯贯通口42e。此外,在各突出方向延伸突出部分42b中的第二方向X上的中央部,形成有卡合销42d所贯通的向振动方向延伸的长孔42c,并且,在各突出方向延伸突出部分42b的内面,沿第二方向X形成有第一环形槽42f。后述的第一联杆构件43a以及第二联杆部43b各自具有的第二卡合突起43g、43h移动自如地卡合在该第一环形槽42f。
如图6所示,联杆部43具有第一联杆构件43a和第二联杆构件43b。第一联杆构件43a和第二联杆构件43b为几乎相同的形状,在第一方向Y上具有超过动铁芯41a的直径的厚度。
第一联杆构件43a在靠近第二联杆构件43b的一端部43c,形成有在第一方向Y上相互分离的一对夹片43c′、43c′,在该一对夹片43c′、43c′分别形成有卡合销42d所贯通的销贯通孔43c1。此外,在第一联杆构件43a的另一端部43d,形成有在第一方向Y上相互逆向突出的第一卡合突起43d1。进而,在第一联杆构件43a的长边方向中央部,与第一卡合突起43d1并列且相互逆向突出地形成有第二卡合突起43g。
第二联杆构件43b也同样在靠近第一联杆构件43a的一端部43e,形成有各自形成有销贯通孔43e1的一对夹片43e′、43e′,在第二联杆构件43b的另一端部43f,形成有在第一方向Y上相互逆向突出的第一卡合突起43f1。此外,在第二联杆构件43b的长边方向中央部,相互逆向突出地形成有第二卡合突起43h。
在动铁芯41a的突出方向Z1上的端部,形成有销贯通孔41b。动铁芯41a经由铁芯贯通口42e插入电磁连结部42内,销贯通孔41b附近由第一联杆部的夹片43c′、43c′以及第二联杆部43b的夹片43e′、43e′从第二方向X夹住。此时,第一联杆部的夹片43c′、43c′的一方插入第二联杆部43b的一对夹片43e′、43e′之间,并且,第一联杆部的夹片43c′、43c′的另一方插入第二联杆部43b的一对夹片43e′、43e′的外侧。
卡合销42d贯通分别形成于相互重合的第一联杆部的夹片43c′、43c′以及第二联杆部43b的夹片43e′、43e′上的销贯通孔43c1、43e1,以及动铁芯41a的销贯通孔41b。此外,卡合销42d两端部插入形成于电磁连结部42的长孔42c,从而与长孔42c卡合。
螺旋弹簧46在卷绕在动铁芯41a上的状态下,一端与卡合销42d抵接,另一端与图5(c)所示的螺线管主体41c抵接(或接近),同时收容在夹片43c′、43c′(43e′、43e′)之间。由此,经由卡合销42d,动铁芯41a与联杆部构件43a、43b相互连结。
活塞固定部44具有:可动侧基部44a,其为与如图2所示的敲打面21a大致平行的板状构件;返回方向延伸突出部分44b,分别从可动侧基部44a的四角向返回方向Z2延伸;以及活塞覆盖部分44c,从可动侧基部44a的四边向突出 方向Z1延伸。在可动侧基部44a的中心部,如图6所示,在动铁芯41a向突出方向Z1突出时,形成有联杆部43的夹片43c′、43c′局部进入的开口44d。在返回方向延伸突出部分44b的内面,沿着第二方向X形成有第二环形槽44e。分别形成于第一联杆构件43a以及第二联杆构件43b的第一卡合突起43d1、43f1在槽内可移动自如地与该第二环形槽44e卡合。
在活塞覆盖部分44c,于多个位置形成有朝着返回方向Z2被切口的切口44g。活塞覆盖部分44c如图4所示,经由该切口44g与从后述的活塞45的螺栓保持部45a向圆周方向外侧延伸的活塞被固定部45c卡合。此外,在活塞覆盖部分44c以及活塞被固定部45c,沿着第一方向Y形成有定接孔44f、45d(参照图5(b))。活塞固定部44以及活塞45在活塞覆盖部分44c和螺栓保持部45a的返回方向Z2侧的端部嵌合的状态下,通过往定接孔44f、45d中插入未图示的螺栓等相互固定。
如图4、5所示的活塞45以使敲打面21a(参照图2)位于前端的方式支承液体用收容部12并且能向振动方向移动,具有瓶体保持部45a和活塞被固定部45c。
瓶体保持部45a为朝着头部11开口的有底大致圆筒状的部件。在瓶体保持部45a的侧面设有可卡定液体用收容部12的卡定爪45b。卡定爪45b构成为伴随着装卸,由于来自液体用收容部12的按压而可以朝着瓶体保持部45a的外侧发生弹性变形。因此,液体用收容部12一方面以插入瓶体保持部45a内的方式,经由卡定凹部12a(参照图3)卡定于卡定爪45b,另一方面,通过被插入部25或其附近被握紧并以一定以上的力向突出方向Z1拉动,可以从瓶体保持部45a中拔出。
在此,如图7所示,电磁致动器41为返回方向Z2侧的一端被堵住的非贯通型电磁致动器,其结构为当动铁芯41a移动到与螺线管主体41c抵接时停止,并且是在向未图示的线圈通电时将动铁芯41a向返回方向Z2上拉的单动式电磁致动器。当动铁芯41a受到向返回方向Z2的吸引力时,卡合销42d沿着长孔42c向返回方向Z2移动,并且,插入卡合销42d的第一联杆构件43a的一端部43c以及第二联杆构件43b的一端部43e向返回方向Z2移动。由此,图6所示的第一联杆构件43a的另一端部43d以及第二联杆构件43b的另一端部43f经由第一卡合突起43d1、43f1传递往突出方向Z1的力给第二环形槽44e,如图7(a)所 示,活塞固定部44以及活塞45一体地向突出方向Z1突出,头部11突出至比保护罩5的突出端5′稍微突出的位置。此时,在电磁连结部42的固定侧基部42a和活塞固定部44的返回方向延伸突出部分44b之间的振动方向上形成有间隙L。此外,螺旋弹簧46压接在卡合销42d和螺线管主体41c之间而积蓄弹力。
之后,当向电磁致动器41的通电变成OFF时,通过螺旋弹簧46的弹力对卡合销42d赋予向突出方向Z1的力。由此,插入卡合销42d的图6所示的第一联杆构件43a、第二联杆构件43b以及动铁芯41a向突出方向Z1移动,由第一联杆构件43a的另一端部43d以及第二联杆构件43b的另一端部43f经由第一卡合突起43d1、43f1传递往返回方向Z2的力给第二环形槽44e。如此通过将螺旋弹簧46用于动铁芯41a的释放(返回),即使在例如倾斜的状态下使用污渍去除装置100,如图7(b)所示,活塞固定部44以及活塞45也一体地向返回方向Z2可靠地移动,头部11被抬起规定尺寸(在本实施方式中约5mm)。然后,电磁连结部42的固定侧基部42a和活塞固定部44的返回方向延伸突出部分44b相互抵接,或者往动铁芯41a的突出方向Z1的移动停止。
通过重复这样的动作使头部11振动(振幅运动)。
在此,在电磁致动器41赋予动铁芯41a远离头部11的方向,即向返回方向Z2的吸引力的情况下,电磁致动器41在已将动铁芯41a向返回方向Z2上拉时发挥最强的力。因此,振动单元4通过具有使头部11往动铁芯41a的位移方向相反的方向突出的联杆机构40,在动铁芯41a被吸引向返回方向Z2时能使头部11突出(推出),能提高敲打力。
在本实施方式中,可在主体壳体33的前端部33b替换安装于电磁致动器41的工作行程的范围内振动方向长度(高度)不同的多个保护罩5、5x。
电磁致动器41在头部11的敲打面21a与例如放置在台上的衣物C等抵接后,即使是在工作行程的范围内,动铁芯41a的上拉也会在中途被机械式地停止,动铁芯41a的工作行程变短。因此,在将保护罩替换为比保护罩5的振动方向长度短例如2mm左右的保护罩5x的情况下,如图7(c)所示,动铁芯41a未被上拉到与螺线管主体41c抵接的位置就中途停止,电磁致动器41的拉动尺寸未达到最大。然后,动铁芯41a从上述位置,同图(d)所示,被螺旋弹簧46向突出方向Z1推出。由此,电磁致动器41的工作行程变短,头部11赋予衣物C的敲打力与使用保护罩5的情况相比变弱(变小)。
这样,在使用保护罩5,使电磁致动器41的拉动尺寸能达到最大的情况下,工作行程为例如4mm左右,敲打力变强。另一方面,在使用保护罩5x,拉动尺寸未达到最大的情况下,工作行程为例如2mm,敲打力变弱。
采用这样的结构,不对电磁致动器41进行电切换,而是通过替换安装在主体壳体33的保护罩5、5x,能变更从主体壳体33的前端部33b到衣物C的距离,能机械式地变更电磁致动器41的工作行程。当为了调整敲打力而想要通过例如控制基板34等电气式调整工作行程时,虽然有部件数变多、装置的尺寸变大的可能,但通过采用可替换安装长度不同的多个保护罩5、5x的结构,能实现装置的小型化,并且能调整头部11施加于衣物C的敲打力的强度。
在本实施方式中,进一步地,当操作按钮(切换部)33d(参照图1)被操作后,通过配置在电池32的相邻接位置的控制基板34(参照图2)改变电磁致动器41的动作频率,能改变头部11的振动速度(敲打速度)。由此,能对应衣物C的种类,调整敲打力的强度以及速度。例如,能实现敲打力弱且速度缓慢的柔洗和敲打力强且速度快的猛洗等多个洗涤模式。
以上,虽然就本发明的一个实施方式进行了说明,但各部分的具体结构不只局限于上述的实施方式。
例如,虽然本实施方式为在主体壳体33上可装卸振动方向长度不同的多个保护罩5的结构(交换式),但并不局限于这样的结构,也可以采用在主体壳体以及保护罩上形成有能在电磁致动器41的工作行程范围内变更从主体壳体的前端部突出的保护罩的长度的变更部的结构。
作为形成有变更部的具体结构,对图8所示的安装方向指定式的保护罩5y进行说明。图8(a)是表示主体壳体33′以及保护罩5y在分解状态下的立体图。图8(b)、(c)是表示将保护罩5y安装在主体壳体33′的状态下的主视图以及纵剖图。
如图8(a)所示,保护罩5y通过基端部5a的一部分被切成大致长方形,从而沿着基端部5a的圆周方向在等距的4处位置形成有深度不同的多个凹部5a1、5a2。这些凹部5a1、5a2形成为:相对较深的第一凹部5a1形成于相互对应的两处,相对较浅的第二凹部5a2形成于相互对置的两处。此外,在基端部5a,在从第一凹部5a1以及第二凹部5a2往突出端5b侧偏离规定距离的位置,内圆周面5a′下凹地形成有后述的爪部33c2所卡合的扣合部5c。
在主体壳体33′的前端部33c形成有对应第一凹部5a1的形状的凸部33c1。此外,在比前端部33c的外圆周面33c′上凸部33c1更靠近开口端33a′侧形成有可弹性变形的爪部33c2。
第一凹部5a1、第二凹部5a2以及爪部33c2构成能变更保护罩5y从主体壳体33′的前端部33c突出的长度的变更部A。如图8(b)所示,当以使第一凹部5a1和凸部33c1卡合的方式将保护罩5y嵌合于主体壳体33′时,同时爪部33c2与扣合部5c卡合。此时第一凹部5a1和凸部33c1相互无间隙地卡合,主体壳体33′和保护罩5y在振动方向上紧贴。
另一方面,在将保护罩5y暂时往突出方向Z1拉动以解除第一凹部5a1和凸部33c1的卡合的状态下,通过使保护罩5y相对于主体壳体33′往圆周方向旋转90°,再次使保护罩5y靠近主体壳体33′,能嵌合第二凹部5a2和凸部33c1。在这种情况下,如同图(c)所示,由于只有凸部33c1的一部分(前端部)与第二凹部5a2卡合,保护罩5y未插入主体壳体33′很深,因此保护罩5y的突出长度变长至对应的长度。在这种情况下,爪部33c2与扣合部5c卡合,由此保护罩5y和主体壳体33′相互固定。
像这样,在主体壳体33′的前端部33c作为变更部A形成有向头部11的轴线方向延伸的凸部33c1,并且,在作为罩部的保护罩5y的基端部5a作为变更部A形成有比具有大致整个凸部33c1所卡合的深度的第一凹部5a1以及该第一凹部5a1的深度浅的第二凹部5a2,在将凸部33c1与第一凹部5a1卡合的情况和与第二凹部5a2卡合的情况下,能够变更保护罩5y的突出长度。
由此,当将保护罩5y安装在主体壳体33′时,通过使相对较深的第一凹部5a1和凸部33c1卡合,或使相对较浅的第二凹部5a2和凸部33c1卡合,能变更从主体壳体33′的前端部33c突出的保护罩5y的长度,机械式地变更电磁致动器41的工作行程(吸引行程),能以一个保护罩5y轻易地调整敲打力的强度。
此外,在主体壳体33′的前端部33c形成有可弹性变形的爪部33c2,并且,在保护罩5y的基端部5a,在凸部33c1与第一凹部5a1或第二凹部5a2卡合的位置形成有与爪部33c2扣合的扣合部5c。
由此,能使爪部33c2和扣合部5c卡合,将保护罩5y固定安装在主体壳体33′,能在污渍去除操作中防止保护罩5y从主体壳体33′脱离。
需要说明的是,还可以采用在主体壳体33′的前端部33c形成有第一凹部5a1以及第二凹部5a2以及扣合部5c,并在保护罩5y的基端部5a形成有凸部33c1以及爪部33c2的结构。
进而,还可以采用在主体壳体或保护罩部的任意一方的外圆周面上,作为变更部形成有螺钉部,并且,在主体壳体或保护罩的任意一方的内圆周面上,作为变更部形成有与螺钉部对应的螺母部,可通过增减螺钉部拧入螺母部的拧入量而能变更保护罩的突出长度的结构(螺旋式)。
采用这样的结构,由于能将主体壳体或保护罩的一方拧入另一方进行安装,因此能连续地变更从主体壳体的前端部突出的保护罩的长度,能以一个保护罩轻易地调整敲打力的强度。
进而,还可以采用在保护罩的前端部,补充安装其他的盖罩部件,由此调整保护罩的突出长度的结构。
此外,虽然上述实施方式的污渍去除装置100是将头部11的敲打面21a朝向下方进行使用的装置,但也可以构成为可将敲打面21a朝向横向进行使用。在这种情况下,动铁芯41a也能够通过螺旋弹簧46向突出方向Z1稳定地推出。
进而,在上述实施方式中,虽然通过保护罩5、5x、5y等调整电磁致动器41的工作行程,但并不局限于这样的机械式的结构,也可以通过电气式控制,调整电磁致动器41的工作行程。此外,也可以构成为不夹装联杆机构40,头部11在动铁芯41a被吸引时突出。
此外,在上述实施方式中,作为液体可以使用洗涤剂混合液,在这种情况下,由于在污渍去除操作中洗涤剂被持续供给到衣物C的污渍部分sp,因此洗涤剂不会因气化、飞散等而从污渍部分sp消失,可以维持高污渍去除效果。
另外,进一步地,构成上述污渍去除装置100的构件的材质不局限于各附图的阴影线所示的材质。
其它的结构也可以在未脱离本发明的技术精神的范围内进行各种变形。
